| Abstract: The various technologies presented herein relate to mitigating or
reducing sidelobe levels during operation of an antenna array. Power
coefficients operating across an antenna array are tapered to facilitate
a power concentration at central region of the antenna array while power
coefficients of a lower magnitude are generated at the periphery of the
antenna array. Power coefficient variation can be effected by at least
one of electrical path length, number of antennas being powered in a
particular antenna subarray, a number of T-splitters incorporated into an
electrical path servicing an antenna, etc. Electrical coupling of a
pre-T/R stripline and a post-T/R stripline can be achieved in conjunction
with operation with a dielectric layer, wherein the dielectric layer acts
as a dielectric at the K.sub.u frequency band. Further, phase delay can
be applied to at least one electrical signal to facilitate concurrent
delivery of power across the antenna array. |
